Someone at another on-campus fraternity house, Phi Kappa Theta, called 911 around 8:30 a.m. about a student found there unresponsive, Jacobs said.

Jacobs said campus police and the county Medical Examiner’s Office were called in to investigate.

The Medical Examiner’s Office said Barzanji was found dead in bed. The cause of death has not been determined pending an autopsy, but Jacobs said a preliminary investigation does not indicate foul play.

Barzanji’s Facebook page said he worked as a server at a P.F. Chang’s restaurant and graduated from West Hills High School in Santee in 2009. He said on his page that he was named after a mountain, and people usually called him “BB.”

A campus newsletter, “@state,” listed Barzanji last fall as recruitment director for the Interfraternity Council.

“We just care for each other,” said Luis Frias, 19, who lives on Fraternity Row but would not say which house he was affiliated with. “It doesn’t matter what fraternity or sorority you are. We all care for each other. We’ll get through it, but this is devastating for everyone.”

University President Elliot Hirshman issued a statement saying, “We are deeply saddened by the news of the death of one of our students this morning. Any loss of life in our community is tragic and I encourage each of you to support each other during this difficult time.”

Students were offered counseling through university counseling and psychological services.

Erin Vierra, 21, who lives and works near Fraternity Row, said she learned of the death in the early afternoon from Facebook.

“I heard a lot of sirens this morning,” the 21-year-old senior said as she stood behind the cash register at Porter’s Market on campus. “But I didn’t know what it was about. I always hear a lot of sirens in this area.”

Juliana Todesco, a 22-year-old senior, said the death had not caused a stir among students.

By early afternoon, there were no signs of police activity around the fraternity house.

But Don Bower, 53, who lives near SDSU and works out at the Aztec Recreation Center, said when he walked by in the morning, he saw officers interviewing one young man sitting on a curb near the house and other officers interviewing a group of young men on a balcony behind the gates that surround Fraternity Row.

Jacobs said authorities do not know if the death had anything to do with the Phi Kappa Theta fraternity.

“Based on (police) findings, the university will take action if necessary,” Jacobs said. “But at this point, we don’t know the circumstances.”
